What it means: The 49ers have won three straight games. Their point total Sunday was their lowest in the win streak. San Francisco is now 4-2 with the easier part of its schedule upcoming. The 49ers were not perfect, but they made big plays on offense and forced four turnovers. San Francisco has forced double-digit turnovers during the win streak. All seems to be going well for the 49ers after they stumbled in Weeks 2 and 3.

Stock watch: San Francisco tight end Vernon Davis had a huge game. He had 180 yards receiving, which is the tied for the third highest total by a tight end in the NFL in the past 20 years. The 49ers don't have a lot of receiving weapons, but Davis got open and quarterback Colin Kaepernick got the ball to him. The 49ers' run offense also came up big on an epic 18-play, 83-yard drive made the score 29-20 with 6:35 to go. Most of the yardage was gained on the ground. The stock is rising for the 49ers' rookies. First-round pick Eric Reid had an interception and a fumble recovery. Third-round pick Corey Lemonier had a sack for a safety and a forced fumble.

Injuries on defense continue: Nose tackle Glenn Dorsey went out early with a hamstring injury. Dorsey was playing well this season. He was jogging on the sideline, so perhaps the injury will not be serious. The 49ers can't afford another extended injury on defense, especially the line. Dorsey was taking over for Ian Williams, who went out for the season with a leg injury in Week 2. Ray McDonald is playing through a biceps injury. Dorsey's replacement, Tony Jerod-Eddie was banged up late in the game. If Dorsey's injury lingers, the 49ers may be forced to push rookie Quinton Dial to the field. He is eligible to practice this week after starting the season on the PUP.

What's next: The 49ers travel to Tennessee to play the Titans, which lost to Seattle on Sunday. After playing in Nashville, the 49ers head to London for a week to prepare for the Jaguars to finish their AFC South slate. Yes, two winnable road games are on the horizon for the 49ers.
